Product details

2.93V threshold — the rail it watches

The TPS3838K33DRVR is a single-channel voltage supervisor from TI's TPS3838 family, monitoring a 2.93V threshold with an active-low, open-drain reset output. This threshold targets 3.3V nominal rails — it asserts reset when the supply drops below 2.93V and holds it low for a minimum 10 ms timeout after the rail recovers.

The 6-WSON package is a common footprint across TI's supervisor line, so a pin-compatible alternate within the TPS3838 family (different threshold voltage) is a straightforward swap if the monitored rail changes.

Frequently asked questions

What is the difference between TPS3838K33DRVR and TPS3838K33DRVT?

The suffix indicates the packaging and reel quantity. TPS3838K33DRVR is supplied in Tape & Reel (TR) — typically a larger reel quantity for production. TPS3838K33DRVT is Cut Tape (CT) — a smaller quantity for prototyping or low-volume builds. The silicon and electrical specs are identical.

Can TPS3838K33DRVR be used in automotive applications?

However, the evidence does not list AEC-Q100 qualification, so it is not formally automotive-grade. For under-hood or safety-critical automotive use, a qualified supervisor should be selected.
